RULING FOUNTAIN-PEN.

, Application filed March 2, 1914.

To all ac/1.0m it may concern.

Be it known that I, GEORGE C. Eccnns, a citizen of the United States, residing at Bovill, in the county of. Latah and State of Idaho, have invented new and useful Improvements in Ruling Fountain-Pens, of which the following is a specification.

This invention relates to improvements in ruling fountain pens. I

It is one of the objects of this invention to provide a pen of this character with pen blades and a feeder which are mounted in the handle byyielding means in such a manner that said means willfunction to support both the pen blades and the feeder in position, with respect to the handle.

A further object is to provide a novel construction whereby said means will not only function to support. said, pen blades and feeder, but also, to close the 'handle against leakage of ink therefrom.

Further objects and novel features of the invention will be more fully describedin the accompanying drawin and will be more particularly pointed out in and by the appended claims.

In the drawing, Figure 1 is a view in elevation of my improved ruling pen with the cap omitted. Fig. 2 is a sectional view, partly in elevation, on line 22 of Fig. 1. Fig. 3 is a view similar to Fig. 2, taken on line 3-3 of ig. 2. Fig. 4 is a sectional view of the feeder, taken on line 4-al of Fig. 3. Fig. 5, is a sectional view on line 55 of Fig. 3.

Like characters of reference designate similar parts throughout the different figures of the drawing.

As illustrated, 1 designates a hollow tubular barrel or handle having one end open and adapted to receive the fluid, which is to be used in the pen. A cap 2 is provided to protect the pen blades and fit over the handle 1, as indicated in Fig. 2.

I provide opposing ruling pen blades 3, which are bowed, as indicated at 4, to provide the necessary resiliency for maintaining the terminal ends 5 in close contact with each other. The terminal ends 5 are in the form of flat bladedike portions, which are provided with longitudinally disposed slits 6 extending inwardly from said ends wherethrough the ruling fluid passes to the ruling ends. The blades 3 converge from the bowed portions 4 to the pen or blade ends 5, and said blades converge, as indicatedat Specification of Letters Patent;

7 from the bowed portions 1, rearwardly. At the terminal of such latter convergence, the pen blades extend outwardly, as at 8, and the same are provided with extensions 9 which closely fit against the interior of the barrel or handle 1.

My improved feeder comprises an elongated solid strip 10, which is preferably oval in crosssection and which I have" shown provided with exteriorly and longitudinally disposed recesses 11, which form feeding ducts. The feeder10 is disposed between the pen blades and extends approximately to the terminal ends thereof or as nearly to the terminal ends as is possible in orderto permit said ends to be disposed in engagement with each other. As illustrated more particularly in. Fig. 3, the end of the feeder terminates near the bases of the slits 6 and con tacts with the pen blades. 1

In order to mount the feeder between the pen blades, I provide means in the form of afpacking disk 12, which is of yielding material. and which is held in place between the extensions 9, the portions 8 forming abutments for the packing means 12. The packing means is suitably apertured for projection therethrough of the feeder 10, so that the latter will be mounted in the packing 12 and will be held against displacement from a true axial position by engagement with the converging terminal ends of the blades, it being my purpose to mount the feeder at two longitudinally spaced points. I preferably provide packing 12 which is sufficiently soft to snugly embrace the feeder 10, but which is not sufficiently yielding to project into and fill the ductsll and thereby interfere with proper feed of the fluid. The feeder 10 projects inwardly past the packing 12 so as to always be in effective fluid receiving proximity with the contents of the handle 1.

It will be seen from the foregoing that the packing 12 constitutes a feed passage closure for the open end of the handle inasmuch as it functions to close the open end of the handle except for feed passage of the fluid in the feed ducts.

By reason of the fact that ducts 11 are provided on opposite sides of the feeder 10, it will be seen that the pen will be operative irrespective of the pen blade which happens to be lowermost when the pen is positioned for use.

I have found in practice that the feed provided by my invention is so efficient that when the, pen blades initially engage the paper a full broad line, equal to the width of the pen blades will result from initial contact of the blades throughout the length of the line drawn. Furthermore, by locating the slits nearer the margins of the pen blades than to the center thereof, I find that the line drawn is never ragged on the edges but is continuous and unbroken throughout its width.

While I have herein shown and described one specific form of my invention, I do not wish to be limited thereto except for, such limitations as the claims may import.

I claim 1. In a fountain ruling pen, a hollow handle for the fluid, a pen blade structure mounted in the handle and having bowed 2. In a fountain ruling pen, a hollow handle for the fluid, opposed pen blades projecting from the handle and having extensions closely fitting the interior of the handle, a feeder extending from the interior of the handle outwardly between said pen blades, and a packing of vielding material interposed between said extensions and embracing the feeder to support the latter and said blades in position, substantially as described.

3. In a fountain ruling pen, a hollow handle for the fluid, independent pen blades projecting from the handle and having extensions projecting into the interior of the handle, a feeder, and handle stopper means of yielding material disposed inside of said handle and engaging the latter and said blades and feeder to hold said blades and feeder in position and close the handle, sub stantially as described.

In testimony that I claim the foregoing as my own, I hereby affix my signature in the presence of two subscribing witnesses.
